Abstract:
This paper presents a solution to panoramic image stitching of two images with co-
inciding optical centers, but unknown focal length and radial distortion. The algorithm
operates with a minimal set of corresponding points (three) which means that it is well
suited for use in any RANSAC style algorithm for simultaneous estimation of geometry
and outlier rejection. Compared to a previous method for this problem, we are able to
guarantee that the right solution is found in all cases. The solution is obtained by solving
a small system of polynomial equations. The proposed algorithm has been integrated in
a complete multi image stitching system and we evaluate its performance on real images
with lens distortion. We demonstrate both quantitative and qualitative improvements
compared to state of the art methods.
